PORTUNUS PELAGICUS FROM MORETON BAY, EASTERN AUSTRALIA Jefrey D.Shields ABSTRACT Fifteen parasites and symbionts were found in the tissues, in the branchial chambers, and on external surfaces of the sand crab Portunus pelagicus. (Ecclesiastical) IPA(key): /peˈla.d͡ʒi.kus/, [pɛˈlaː.d͡ʒi.kus] Niem (eds.). Three gill structures were monitored in the present study: primary gill (branchial stem), secondary gill (gill lamellae), and distal tips. Chelae elongate (more in males than in females) with conical tooth at the base of fingers; 3 spines on the inner margin of the merus.
